About Booking App Builder
Build a booking and client app with AI: your own booking rules, client sign-in, email and push reminders, deposits and subscriptions, on the web and as a phone app.
What is Floot?
Floot is an AI app builder that makes booking apps with your own rules, client logins, reminders and deposits, so your booking system fits your business instead of the other way round.
Off-the-shelf booking tools work until your rules don't fit: a staff member who only does certain services, packages of sessions, a deposit for new clients only. With Floot you describe how your business books, and AI builds that app, with a database, client accounts and reminders included.
Why build it with Floot?
Off-the-shelf booking tools work until your rules don't fit their settings. With Floot you describe how your business books and get an app built around it.
How Floot works
Add Floot to the AI you already use from its listing in the Claude or ChatGPT directory, or the Cursor Marketplace. There is no address to copy.
- Write down how you book today: services, staff, hours, rules.
- Describe it to Floot from ChatGPT, Claude or the Floot editor.
- Book a few test appointments in the preview.
- Publish and share the booking link with clients.
For example, you could start with this prompt:
Build a booking app for my spa. Services have different lengths and need a 15-minute cleanup gap. Each therapist offers only some services. New clients pay a $20 deposit. Send an email reminder 24 hours before.
What can you use Floot for?
- Salons and spas: Services of different lengths, cleanup gaps and per-therapist services.
- Coaches and consultants: Session packages, client notes and follow-ups.
- Rentals and classes: Capacity limits, waitlists and deposits.
Who is it for?
Service businesses whose booking rules don't fit standard booking software.
Who founded Floot?
Floot was founded by Yujian Yao, who is its CEO.
Is Floot backed by Y Combinator?
Yes. Floot is backed by Y Combinator and was part of the Summer 2025 batch (YC S25).
What does Floot include?
- Your booking rules: Service lengths, buffers, who can do which service, packages and waitlists are written into your app, not squeezed into settings.
- Client accounts: Clients sign in to book, reschedule and see their history. No outside account needed.
- Reminders that send themselves: Scheduled jobs send email or push reminders before each appointment, with nobody online.
- Deposits and packages: Floot Payments handles checkout and subscriptions, paid out through Stripe.
- On their phones: Publish to the web and, if you want, the App Store and Google Play.
